This session examines how California can address housing affordability, climate resilience, and construction waste through practical, scalable applications of circular construction. Drawing from active multifamily, infill, wildfire-rebuild, and interim housing projects, the presentation focuses on real-world solutions rather than theory. Attendees will learn how industrialized building systems—such as off-site fabrication, panelized construction, and digitally prefabricated components—can significantly reduce construction timelines, improve cost predictability, and minimize material waste while meeting California’s stringent energy, fire-safety, and performance standards. The session explores how combining light-gauge steel structural systems, high-performance building envelopes, and advanced fabrication methods, including 3D-printed components made from recycled materials, supports durable housing across diverse climates, including wildfire-prone Wildland-Urban Interface communities. The presentation highlights collaborative delivery models involving developers, architects, manufacturers, and public agencies, with case examples spanning urban multifamily developments, missing-middle infill housing, custom multi-story residential projects, and rapidly deployable interim housing for unhoused populations. These examples demonstrate how circular construction approaches can advance environmental goals while supporting equity, workforce efficiency, and long-term community resilience. The session also addresses practical considerations such as permitting, coordination with architects of record and general contractors, and integrating innovation into established development workflows without increasing risk. Participants will leave with actionable insights into how circular economy principles can be applied today to deliver faster, more resilient, and more predictable housing outcomes across California.
